Internal Effect of High Glucose Levels Peer Review
Introduction
Hyperglycemia is mutual in daily practice with hospitalized individuals, present in nearly 25–35% of Italian patients at admission.1 The prevalence is dictated by the loftier prevalence of diabetes in the elderlyii (much more commonly admitted than young individuals) and by stress-induced hyperglycemia, i.e., the elevation in claret glucose levels during periods of affliction, resulting in remarkable metabolic stress.iii Mild-to-moderate stress hyperglycemia is protective, providing fuel for the immune system and encephalon at a fourth dimension of stress; still, persistent hyperglycemia and insulin resistance may exist potentially deleterious in the long run,4 direct contributing to agin outcomes via endothelial dysfunction, increased free radical production (oxidative stress), inflammatory responses, vascular and immune dysfunction.v
A human relationship between admission plasma glucose concentration and in-hospital mortality has long been established. Hyperglycemia has been associated with increased risks of congestive middle failure and mortality, both during the acute phase and the long-term follow-up of myocardial infarction,four of bloodshed for customs-caused bacteremia,6 of acute respiratory failure in subjects with chronic obstructive pulmonary affliction,7 as well as of mortality, poor functional recovery and transformation into hemorrhagic stroke in subjects with ischemic vascular illness.eight,ix
Acute hyperglycemia following traumatic injury has besides received a lot of attention; traumatic injuries induce stress hormone secretion, largely mediated by glucagon,x in turn promoting oxidative stress and insulin resistance, finally resulting in hyperglycemia.11–14 Access blood glucose represents a clinically useful predictor of mortality and infectious outcome in traumatically injured patients,15,16 and achieving normoglycemia in the early postal service-traumatic period may reduce the chance.17
The definition of stress hyperglycemia remains difficult at the time of the event. Without evidence of prior diabetes, hyperglycemia during acute events could too stem from undiagnosed diabetes, where the elevated claret glucose remains an independent risk factor for complication. A recent study divers relative hyperglycemia (stress hyperglycemia ratio [SHR], ie, access glucose divided by the estimated average glucose derived from glycosylated hemoglobin) as a tool to discover stress hyperglycemia.18 Equally such, SHR controls for background claret glucose and was shown to exist a amend biomarker of disquisitional affliction than accented hyperglycemia.eighteen
We tested the reason(s) for hyperglycemia in a consecutive series of subjects undergoing orthopedic surgery in order to determine the presence of stress hyperglycemia and its association with the final outcome. Information may be relevant for tailored intervention and proper management.
Materials and Methods
Patients
This was an observational, prospective cohort study carried out in two Orthopedics units of the Academy Hospital Sant'Orsola-Malpighi and Rizzoli Orthopedic Institute of Bologna (Italy). The study included consecutive patients anile ≥18 years, admitted with injuries requiring acute intervention and hyperglycemia at the time of access. Patients with orthopedic injuries non-requiring operative intervention, under corticosteroid treatment or critical illnesses were excluded.
The demographic and clinical data at entry are reported in Table 1. The distinction between minor or major surgery was obtained by the utilise of current tables of anesthesia and resuscitation Units (Supplementary Fabric). Following the demonstration of hyperglycemia, all cases were insulin-treated until glucose normalization or discharge from hospital, when they were referred to specialized diabetes units. The whole study received approving past the ethical committees of the participating institutions and was conducted according to the Helsinki declaration. The patients signed an informed consent to participation and anonymous data drove.

Methods
Admission glucose was recorded as the first glucose measurement after admission; hyperglycemia was defined as: a) fasting glucose values ≥126 mg/dL (7 mmol/50) from venous claret or capillary claret; b) capillary or venous blood glucose levels ≥144 mg/dL (eight mmol/Fifty) in patients tested in non-fasting conditions.
Patient information was recorded and included demographic characteristics, medical history, claret glucose on admission and during infirmary stay, HbA1c, concurrent medical diagnoses, diet and/or drug treatment for glucose control, length of stay, and hospital issue. From patient history, we calculated the age-adjusted Charlson Comorbidity Index.19 During the hospital stay, insulin treatment was immediately instituted and daily blood glucose was monitored with four bed-side capillary glucose measurements (three pre-meal blood glucose measurements and one‒2 hours after the evening meal) in pre- or mail-surgical days or more frequently during the day of surgery.
Total hospital stay, needs for admission to intensive care unit (ICU) and re-intervention were recorded, as well as adverse events, with special consideration for local and systemic infections and cardiovascular (CV) events. Peri-operative infectious complications were categorized every bit pneumonia, urinary tract infections, and surgical site infections. Surgical-site infection was defined every bit whatsoever instance that required reoperation for an infection at the site of the alphabetize performance and was confirmed by the presence of either positive intra-operative cultures, pathology specimens with microbiologic pathogens, or visible gross purulence at the operative site.
Laboratory Tests
HbA1c is measured in the whole expanse of Bologna by a unmarried laboratory, certified according to the initial DCCT rules and afterward as from the National Glycohemoglobin Standardization Plan (NGSP). HbA1c was used to detect an unknown diabetic land (HbA1c ≥48 mmol/mol),1 as well as to gauge the average blood glucose concentration before access using the equation: estimated average glucose (mg/dL) = (28.7*HbA1c [%]) – 46.seven.20
Relative hyperglycemia was defined past SHR, calculated equally admission glucose divided by estimated average glucose.18 Values of SHR >1.14 were considered equally indicative of stress-induced hyperglycemia, both in the presence and the absence of previously known diabetes. Using diabetes history, HbA1c and SHR as indicators, we grouped patients into three categories (Figure 1): a) diabetes/no stress hyperglycemia (SHR ≤1.i.xiv); b) diabetes/stress hyperglycemia (SHR >1.fourteen): c) no diabetes/stress hyperglycemia (SHR >1.fourteen).

We also categorized patients with stress hyperglycemia into quartiles of SHR in social club to test the possible incremental role of stress hyperglycemia on the increased chance of complications.
Statistical Analysis
Statistical assay was performed using StatView 5.0™ (SAS Establish Inc., Cary, NC) and SPSS for Windows v.21 (SPSS Inc., Chicago, IL, USA). Continuous variables were reported using hateful and standard departure (SD) or median and interquartile range (IQR), as advisable. Absolute prevalence and percentage were used for categorical variables (dichotomous variables). Differences between continuous variables for the different cohorts were tested for significance using the Isle of man–Whitney U-test. Prevalence in dissimilar groups/subgroups was compared with Chi-squared test or with Fisher's exact examination when appropriate.
A logistic regression analysis was performed to define the clan of stress hyperglycemia with the unlike outcome variables, after adjusting for age, sex, body weight (BMI), comorbidities (historic period-adjCharlson'southward index) and type of surgery. The relative chance of outcome variables was calculated as odds ratios (OR) and 95% conviction interval (CI). P values <0.05 were considered statistically meaning.
Results
Admission Values
Two hundred and 2 patients satisfied the inclusion criteria and were considered in the analysis. Their baseline demographic data are reported in Table 1. The boilerplate body mass index (BMI) was 28.0 kg/m2, in a broad range (from 15.vi to 44.1). Ane hundred and lxx-eight patients had a history of type 2 diabetes, 5 had Blazon 1 diabetes, and nineteen showed hyperglycemia at hospital admission in the absence of a previous history of diabetes. In 13 cases, Hb A1c ≥48 mmol/mol revealed a previously unreported diabetes. Most patients with diabetes were beingness treated with oral glucose-lowering agents alone, 23% with insulin (alone or in combination with oral agents), and the remaining xviii% with the sole diet. In most cases (n = 173, 85.six%), surgical treatment savage within the criteria of major surgery. The average time from admission to surgery was 2.3 days (2.45 days in patients undergoing major surgery, ane.89 days for minor surgery), while 8.vii days was the average time from surgery to infirmary discharge (9.58 days for major surgery; 4.58 days for modest surgery).
Several associated diseases were as well recorded, as were diabetes-related comorbidities (sixteen.3% of total cases). The age-adjusted Charlson comorbidity index was on average 5.2 ± 2.1, median 5.0 points; the score was neither different between genders nor between subjects in the iii different cohorts.
Glucose Values and Categories of Hyperglycemia
The number of cases fitting the dissimilar classes of hyperglycemia are reported in Figure ane.
In 53/196 cases with diabetes (26.5%), hyperglycemia was exaggerated in comparison to the average claret glucose estimated from glycosylated hemoglobin (SHR >1.fourteen) and the patients were considered to accept stress hyperglycemia superimposed to diabetes. SHR was ≥ane.14 as well in the remaining half-dozen cases, considered to represent pure stress hyperglycemia.
In comparison to subjects with diabetes and no stress hyperglycemia (reference) (Tabular array 2), the presence of stress hyperglycemia superimposed to diabetes was characterized past higher blood glucose levels at access, just no systematic differences in HbA1c, age and comorbidities.
 | Table 2 Principal Characteristics and Adverse Events or Complications in Relation to the Presence of Diabetes and Stress Hyperglycemia |
In-Hospital Events
During hospitalization, patients were monitored for the development of mail-operative complications, including the possible demand for a re-intervention, unplanned admissions to ICU and death. At to the lowest degree ane complexity was recorded in 68 cases (33.seven%)(32.2% following major surgery, ane.5% after small surgery). The well-nigh common complexity was systemic infection (22.8% of cases), with/without local infection at the surgical site, which occurred alone in seven.three% of cases.
As to cardiovascular complications, 2.five% of patients adult a coronary result, 3.5% astute heart failure and 5% atrial fibrillation. Simply one patient experienced a transient cerebrovascular accident (0.5%), while no patients developed astute renal failure. Another 5% of cases were complicated by a miscellanea of obstructive airway episodes, acute cholecystitis, respiratory failure, epileptic crises, pericarditis, fractional bowel obstacle and astute liver failure; 2.5% of cases experienced at least 1 hypoglycemic episode. Unplanned access to ICU was required in 5.iv% of patients, while 4 (ii%) required re-intervention. Only one patient (0.5%) died during hospitalization; 43.6% received at to the lowest degree one unit of measurement of packed ruddy blood cells.
The rates of complicating events were different in relation to categories of hyperglycemia. In comparison to subjects with diabetes and no stress hyperglycemia (reference) (Tabular array 2), the presence of stress hyperglycemia superimposed to diabetes was characterized past college rates of cardiovascular events and systemic infections. These complications were very common also in the small group of cases with stress hyperglycemia in the absenteeism of diabetes. When all cases with stress hyperglycemia were grouped, the resulting cohort was also characterized by significantly higher rates of arrhythmias and reintervention (Table 2).
Outcomes
The clan of hyperglycemia category with outcomes is reported in Table 3, where diabetes without stress hyperglycemia was considered as the reference category. In the whole population with diabetes, stress hyperglycemia significantly increased the gamble of adverse events, excluding local infections. In subjects with stress hyperglycemia without diabetes, but the significant clan with cardiovascular events was maintained, with the limits of a express number of cases. When all cases with stress hyperglycemia were merged, stress hyperglycemia was associated with four-time increased hazard of adverse events, over x-time increased risk of cardiovascular events, 4-time risk of systemic infections, six-time increment of other adverse events, without changes in the run a risk of ICU admission, after aligning for confounders. In a sensitivity analysis, SHR every bit continuous variable was associated with an increased risk of adverse events (any events) in the whole population (adjustedOdds ratio [adjOR], 1.25 per 0.x increment; 95% confidence interval [CI], 1.12–1.39; P < 0.0001), irrespective of the presence of diabetes.
 | Table 3 Association of Hyperglycemia Categories with Agin Events in Subjects with/Without a History of Diabetes |
Later exclusion of the five cases with type one diabetes, the association of stress hyperglycemia with complications (any events) (adjOR 4.eleven, 95% CI 1.98–8.51), with systemic infection (adjOR 4.40, 95% CI 2.06–ix.40) and with cardiovascular events (adjOR vi.88, 95% CI ii.42–19.57) was maintained. The same was also true later on exclusion of all insulin-treated subjects (n=26)(any events, adjOR 3.93, 95% CI ane.62–9.54; systemic infection, adjOR 3.93; 95% CI 1.62–ix.54; cardiovascular events, adjOR 8.93; 95% CI 2.70–29.49).
The length of hospital stay was much longer in the presence of stress hyperglycemia (+24.5%; thirteen.three ± vi.2 days vs ten.7 ± seven.nine in subjects without stress hyperglycemia; P = 0.042).
Discussion
The report highlights the importance of stress hyperglycemia in the development of complications in the specific setting of subjects undergoing orthopedic surgery following traumatic injuries. Irrespective of the presence of overt or newly-discovered diabetes, the risk of adverse events increases several times whenever claret glucose exceeds the values corresponding to the measured glycosylated hemoglobin. This condition also requires a different management, considering the longer length of hospital stay and is expected to carry much college costs.
Our assay is based on the assessment of SHR, a tool to notice stress hyperglycemia suggested and validated in a large clinical setting by Roberts et al.18 This tool appears to be particularly useful since it provides an assessment of stress-induced hyperglycemia also in the presence of underlying diabetes, which might mistiness the response to stress. In the original proposal, SHR was demonstrated to be independently associated with critical illness to a much larger extent than accented hyperglycemia, largely driven by diabetes and glucose-lowering treatment.xviii The SHR cut-off to define stress hyperglycemia has never been definitely validated. Nosotros cull a value of 1.14, i.e., the average value previously shown to be associated with an increased rate of agin events.xviii The SHR value also demonstrates a linear result on the occurrence of agin events, forth the whole range of SHR values. In a mail hoc analysis of our population, where subjects with SHR > one.xiv were divided into quartiles, the odds ratios of adverse events progressively increased from iii.82 (2nd quartile) to iv.16 (3rd quartile) and finally to half-dozen.95 (fourth quartile). Similar results were also observed in the original study.eighteen Our results ostend the detrimental effect of this definition of stress hyperglycemia, to be confidently used in future prospective studies. A rapid cess of stress hyperglycemia might be particularly useful in weather where surgery should be carried out without any delay, as in traumatic injuries, and particularly in older patients, where diabetes may ofttimes occur.
Dungan et al suggested that stress hyperglycemia might be a physiological response to stress-induced insulin resistance, via a possible modulation of glucose transporters, independently of diabetes.3 Yet, hyperglycemia per se amplifies the inflammatory response, possibly increasing the gamble of agin events. In our setting the risks for agin events in subjects with stress hyperglycemia in the absence of diabetes are generally elevated compared to diabetes without stress hyperglycemia, although difficult to define due to the limited sample size. In full general, the higher risk of adverse events is confirmed to involve unlike organs and systems, suggesting that a general abnormal response to stress might be the common driver.
If stress hyperglycemia drives complications, the type and target organ is likely to vary according to a specific setting. In surgical patients, the gamble for surgical site infection is particularly disquisitional and adds to the cardiovascular risks previously demonstrated in other settings. Several large studies have consistently associated the presence of diabetes with surgical site infections.21–23 In a large database on 13,272 patients who underwent chief joint arthroplasty between 2001 and 2011, Chrastil et al plant was no increased gamble of infection associated with elevated glycosylated hemoglobin, whereas preoperative hyperglycemia was associated with an increased incidence of perioperative joint infection again in keeping of a major run a risk of stress-induced hyperglycemia.21 In a review article and meta-analysis of surgical procedures, Martin et al institute an increased risk for surgical site infection associated with diabetes (OR, ane.53; 95% CI, i.xi–2.12), and lower values for orthopedic surgery (arthroplasty, OR 1, 26), merely they also ended for a higher risk associated with glucose levels, after controlling for the presence of diabetes.22
The risk of adverse events associated with high SHR was especially elevated in subjects without diabetes, who did non receive whatsoever handling for their hyperglycemia. This points to a possible modulatory effect of glucose-lowering handling on hyperglycemia and opens the question of systematic assessment of blood glucose and immediate and effective treatment with insulin at access, equally suggested by guidelines, independently of the presence of diabetes. Surgical site infections, independently of the presence of diabetes, are universally recognized as quality-of-care indicators.24 In an updated review based on an erstwhile written report from the National Establish for Wellness and Clinical Excellence, Bock et al concluded that information did not support routine preoperative testing for blood glucose or HbA1c in patently healthy developed patients undergoing elective noncardiac surgery. Yet, also in their analysis orthopedic surgery was worth a screening.25 The onetime age of the majority of patients undergoing elective surgery and the multiple comorbidities associated with diabetes are the likely reason for the difference in comparison to other elective surgeries. In our setting insulin handling was immediately instituted in the presence of hyperglycemia at admission according to predefined protocols, but adverse events were nonetheless very common and clustered in subjects with stress-induced hyperglycemia. Tailored glucose-controlling, insulin-administrating programs are needed to keep infection and non-infection complications to a minimum.26 Only a few well-designed controlled studies are available in the orthopedic setting,27 and the implementation of effective procedures in frail hyperglycemic patients by dedicated teams requires special attention.28
Conclusion
Stress-induced hyperglycemia remains difficult to ascertain at time of the event. In the setting of orthopedic surgery, our study confirms that the calculation of the stress hyperglycemia ratio provides a measure with a definite clinical significance. Larger studies are needed to ascertain the precise cut-off of the ratio, both in the presence and the absence of overt diabetes, associated with clinical events, because the prognostic information it provides. It should too be relevant to define how much the persistence of stress hyperglycemia will touch on on adverse events.
